Description

Technical Field

[0001] The utility model relates to the technical field of steering devices, and more specifically to an emergency steering device of a mining dump truck. Background Art

[0002] A mining dump truck is a type of dump truck used in open-pit mines to transport rocks, ores or coal. It has a short haul and a heavy load. It is usually loaded with a large electric shovel or hydraulic shovel and travels back and forth between the mining point and the unloading point. Because of its extra-wide shape and excessive total mass, it is not allowed to travel on the road, so it is also called an off-road dump truck.

[0003] At present, mining dump trucks often travel in mines when they are working. Since mine roads are relatively tortuous, when a mining dump truck encounters a narrow road at a bend while driving, it is easy for the front of the truck to pass through the bend while the rear of the truck cannot pass through when the dump truck turns. At this time, the dump truck is easily stuck at the bend and cannot continue to drive. Therefore, the present application provides an emergency steering device for a mining dump truck, which can assist the rear of the dump truck to complete the steering operation. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an emergency steering device for a mining dump truck to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: an emergency steering device for a mining dump truck, comprising a mounting frame, a hydraulic rod is fixedly mounted in the middle of the bottom of the mounting frame, a steering adjustment mechanism is mounted at the telescopic end of the hydraulic rod, the steering adjustment mechanism comprises a support cover and an arc-shaped guide seat, the top of the support cover is fixedly connected to the telescopic end of the hydraulic rod, the interior of the support cover is arranged on the outside of the arc-shaped guide seat, the top of the arc-shaped guide seat is fixedly connected with an arc-shaped rack, a driving gear is arranged above the interior of the support cover, the driving gear is located above the arc-shaped rack, the driving gear is meshed with the arc-shaped rack, a mounting cover is fixedly mounted above the front side of the support cover, and a motor is fixedly mounted inside the mounting cover.

[0006] Furthermore, bearings are fixedly installed on both sides of the support cover, a rotating shaft is fixedly installed inside the driving gear, both ends of the outer wall of the rotating shaft are rotatably installed inside the bearings, and one end of the rotating shaft extends to the inside of the mounting cover and is fixedly connected to the output end of the motor.

[0007] Furthermore, the front and rear sides of the arc-shaped guide seat are provided with limiting slide grooves, the lower parts of the front and rear sides of the inner wall of the support cover are fixedly connected with limiting sliders, and the outer wall of the limiting slider is slidably connected to the inside of the limiting slide grooves.

[0008] Furthermore, the bottom of the arc-shaped guide seat is fixedly connected to a base, and the bottom of the base is fixedly inlaid with a rubber anti-slip pad.

[0009] Furthermore, a plurality of rollers are installed on the front and rear sides of the bottom of the support cover, and the bottoms of the plurality of rollers are rollingly arranged on the front and rear sides of the top of the base.

[0010] Furthermore, threaded mounting openings are provided at four corners of the mounting frame.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model facilitates the installation of the device under the rear end of the mining dump truck through the setting of the mounting frame. If it is necessary to assist the rear end of the dump truck to complete the steering operation, the height of the device can be adjusted through the setting of the hydraulic rod, and the base can be moved to the ground. At this time, the support cover, the limit slider, the arc-shaped guide seat, the limit slide groove, the base, the arc-shaped rack, the mounting cover, the motor, the rotating shaft, the driving gear, the bearing and the roller cooperate to facilitate driving the support cover to move on the outer wall of the arc-shaped guide seat. The support cover drives the rear end of the mining dump truck to move through the hydraulic rod and the mounting frame, so that it is convenient to adjust the position of the rear end of the mining dump truck when turning, and it is convenient to assist the rear end of the dump truck to complete the steering operation, so as to avoid the situation that when the mining dump truck encounters a narrow road at a bend while driving, the front of the dump truck is likely to pass through the bend while the rear end cannot pass through when the dump truck turns.

[0013] 2. The utility model adopts the setting of a limiting slider and a limiting slide groove to facilitate the limiting and guiding of the support cover, thereby preventing the support cover from detaching from the outside of the arc-shaped guide seat during movement. The setting of the rubber anti-skid pad facilitates the increase of the anti-skid property of the base when it is moved to the ground. BRIEF DESCRIPTION OF THE DRAWINGS
